The sedimentary deposits transported by paleocurrents often provided favorable conditions for the enrichment of modern liquid reservoirs. However, due to limited seismic and well logging data, studies focused on the macroscopic directions of paleocurrents L are scarce. In this study, we obtained a series of well logging data for the sedimentary layers of Es3 Formation in the Chezhen depression. The results indicate the sources of paleocurrents from the northeast, northwest, and west to a center of subsidence in the northern Chezhen depression at that Citation: Gao, Y.; Li, F.; Shi, S.; time.

  • Well Logging
    University of Kirkuk / Faculty of Science / Applied geology department rd 3 year 2020 WELL LOGGING Dr. Radhwan Khaleel Hayder INTRODUCTION: -What is a “Log” and ‘’Well Logging’’. LOG OR WELL LOGGING (THE BOREHOLE IMAGE): - Data are organized and interpreted by depth and represented on a graph called a log (a record of information about the formations through which a well has been drilled). - Visual inspection of samples brought to the surface (geological logs). Example cuttings and corres. - Study of the physical properties of rocks and the fluids through which the bore hole is drilled. - Traditionally logs are display on girded papers. Now a days the log may be taken as films, images and in digital format. - Some types of well logs can be done during any phase of a well's history: drilling, completing, producing or abandoning. -Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral, environmental and geotechnical studies. -The first electrical resistivity well log was taken in France, in 1927. THE IMPORTANCE OF WELL LOGGING: 1-Determination of lithology. 2-Determination of reservoir characteristics (e.g. porosity, saturation, permeability). 3-Determination formation dip and hole size. 4-Identification of productive zones, to determine depth and thickness of zones. 5-Distinguish between oil, gas, or water in a reservoir, and to estimate hydrocarbon reserves. 6-Geologic maps developed from log interpretation help with determining facies relationships and drilling locations. 1 ADVANTAGES AND LIMITATIONS OF WELL LOGGING: Advantages: 1- Continuous measurements. 2- Easy and quick to work with. 3- Short time acquisition. 4- Economical. Limitations: 1- Indirect measurements.

    ID: - 2767738 Automation Provides Unique Insights of The Rock Record and Subsurface Through the Delivery of a Robotic Sample Collection and Analysis Device David Tonner, Diversified Well Logging, Houston TX, USA, Aaron Swanson, Diversified Well Logging, Houston TX, USA, Ron Hollingshead, Diversified Well Logging Houston TX, USA, Simon Hughes, Diversified Well Logging Houston TX, USA , Stephen Seacrest, PetroLegacy Energy Austin TX, USA, Bret McDaniel PetroLegacy Energy Austin TX, USA ABSTRACT Abstract Objectives/Scope: From the very early days of oil and gas exploration, appraisal and development drilling, samples have been collected at the rig by mud logging personnel to conduct a preliminary geological analysis of the rock being drilled. This collection typically involves a sample collection recipient, board or bucket to collect a sample of rock over the desired interval. The sample is then sieved and cleaned in the appropriate way depending on the type of drilling fluid being used. As penetration rates have increased in some instances to more than 400 ft. / hr. the sample resolution has deteriorated exponentially. From an ergonomics perspective, the highest frequency to which a person onsite can collect a sample is once every 20 minutes. At 300 ft. / hr. this translates to 100 ft. of drilled rock. A new device has been developed and deployed which automates this manual process and thus ensures faster and more accurate collection of geological samples of the drilled rock interval. Sample resolutions of 5ft rock intervals have been attained at 400 ft./ hr. This technology has provided an important technological breakthrough and enables reduction of personnel at the rig site with a subsequent reduction in cost and HSE risk, particularly in areas of H2S.

During early exploration phase, the formation evaluation program is carried out by collecting as much subsurface information as possible. This was applied because of available subsurface data to support the development geothermal project are very limited. On the other hand, the program is very influenced and directly involve to the drilling operation that might risks the drilling operation, in term of well stability and well cost perspective. Thus, the effective and efficient techniques are highly required in the making of proper formation evaluation program. The main purpose of formation evaluation is to get a better understanding of subsurface geology and developed geothermal system so the best future strategy of field development can be determined. By doing this evaluation while drilling, it will give an advantage to the drilling operation itself. Knowledge of the real-time drilled formation, in term of its behavior, characteristic, and composition, will help the improvement of drilling performance and increase the well success ratio.

Research on characteristics of a new oil-based logging-while-drilling instrument.

Oil-based mud (OBM) can improve drilling efficiency and decrease operation risks, and has been widely used in the well logging field. However, the non-conductive OBM makes the traditional logging-while-drilling (LWD) method with low frequency ineffective. In this work, a new oil-based LWD method is proposed by combining the capacitively coupled contactless conductivity detection (C4D) technique and the inductive coupling principle.

Firstly, there was presented a short description of selected well logs and methodology of determination of petrophysical parameters use- ful in geothermal investigations: porosity, permeability, fracturing, mineral composition, elasticity of orogeny and mineralization of formation water from well logs. Special attention was allotted to spec- tral gamma-ray and temperature logs to show their usefulness to radiogenic heat calculation and heat flux modelling. Electric imaging and advanced acoustic logs provided with continuous information on natural and induced fracturing of formation and improved lithology recognition. Wireline and production logging were discussed to present the wealth of methods that could be used.
